我正在尝试使用 tikz-tree 绘制大型家庭/目录树。我发现了这个问题在 Stackexchange 中，它几乎可以工作，但并不完全。使用答案中提供的代码，当我的树足够大时，我会得到重叠的文本。如果我不使用更紧密的意图，节点不会重叠，但我不会得到想要的意图（并且树变得太宽）。

对于使用上述代码获得的参考图。我想要的是第一幅图像的节点缩进，而不重叠节点。 使用示例代码获取的图像

任何帮助是极大的赞赏！

答案1

我会使用这个，forest因为它比其他选项更灵活、更强大。特别是，它可以使用更简洁的代码来构造树，而不需要太多的定义技巧。

编辑

根据评论中指定的额外要求，对此进行了编辑以满足两个条件：

  1. 使用新样式将给定级别的所有节点放在同一位置tier，从而确保缩进恒定；
  2. l被指定来控制级别之间的距离（当前设置为15pt- 根据需要调整）。

已edge path进行相应调整，并inner sep指定了保持紧凑而不会太过拥挤。同样，这些可以根据您的要求进一步修改。

\documentclass[tikz,varwidth,border=5pt,multi]{standalone}

\begin{document}
\forestset{
  my tier/.style={% align all nodes on a given level
    tier/.wrap pgfmath arg={level##1}{level()},
  },
}

  for tree={
    grow'=0,
    child anchor=west,
    parent anchor=south,
    anchor=west,

    s sep+=-5pt,
    inner sep=2.5pt,
    edge path={
      \noexpand\path [draw, \forestoption{edge}]
      (!u.south west) +(7.5pt,0) |- (.child anchor)\forestoption{edge label};

答案2

由于 y 距离在全局定义中设置为 -0.5cm dirtree@growth（第 17 行），因此可以在本例中将全局设置更改为 t0 -1cm，或者Overlay, Long text here and Foo通过yshift=xx cm语法手动调整这些重叠节点，如下所示。这是因为手动设置是局部更改，从而使生成的图像紧凑。
